Title: Method for controlling hybrid vehicle drive
Inventor: KURITA SHIGEAKI
IPC: B60L50/16
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a shock generated in a hybrid vehicle having a motor and an engine as vehicle drive sources is large because fuel injection is started simultaneously with the start of cranking when the engine is started by cranking by the motor after the vehicle is started by the motor only in the hybrid vehicle. SOLUTION: When the engine is cranked after starting the vehicle by the motor, a first clutch connecting the motor with the engine is first made half- clutch. Since the engine is cranked by the motor, and is connected with it through half-clutch, a burden applied on the motor when they are connected is small, and a shock generated in the vehicle is small. When the number of revolutions of the engine reaches the number of idling rotation, fuel injection into the engine is started. Since the engine is already rotated by the number of idling rotation, combustion and rotation within one cycle are performed in a stable form in which torque fluctuation is reduced, and the shock generated in the vehicle is reduced.
